FILED JAN. 1919. 2 SHEETS'SHEET 1 Jan. 23, 1923. r 1,443,291 J. G. SWAIN: WHEEL AND DEMOUNTABLE RiMj I FILED JAN. 15 1919. Z'SHEETs-SHEEffZ 70 I ll a shoulder or recess 12 which seats upon an angular rib or rabbeted surface 13 around the face of the wheel. This forms a simple and convenient means for preventingmotation of the clamp plate on the bolt.

The rim may be of any preferred typm that shown being designed to carry a straight-side tire 14, and having a remov able side flange 15 and locking ring 16. The inner tube is shown at 17. The valve stem is designated by the nun'ieral l8 and extends a short distance below the rim. being bent outwardly at its lower end. Tlhis valve stem may be arranged withany suit able type of valve mechanism, and to its outer end may be applied any form of horizontal extension tube which may be pro vided with valve mechanism and adapted to be attached to the inflating pump. in order to receive the outer end of the valve stem 18 and any lateral extension which may be provided for it, the face ofthe wheel is formed wit-h a gutter or channel opening from the face of the wheel and extending to a point beyond the location of the valve stem.

At the sides of the valve receiving gutter, the periphery of the wheel is formed with two lugs or projections 20, and to the under side of the rim are riveted two plates ill at the sides of the lugs, the lugs and plates serving to prevent rotation of the-rim on the wheel. The lugs and plates may be formed in any satisfactory manner but the particular arrangement shown is convenient and economical. In order to allow the rim to be removed laterally, a section of the inner bevel rib is removed, forming a gap 22 which will pass over the driving lugsrltl.

lrlany ot' the details shown and described may be varied within the scope of the invention and l. consider myself entitled to such as .t'airly come within the purview ot the appended claims.

I claim:

1. A wheel structure comprising a wheel body a substantially cylindrical outer surface on said wheel body, a rim seat at one side of the wheel body, a deniountable rim on said wheel seating surfaces on the under side of said rim, the surface on the rear of said rim'restinpon said rim seat, the surface of said wheel having a recess to receive the valve stem, a drivin g lug on the surface oi the wheel at one side of the recess, the said surface on the rear of the rim being apertured to pass over the said driving lug. and a formation on the under side of the rim to cooperate with the drivin c lug.

2. A. wheel structure comprising a wheel body. a substantially cylii'idrical outer surtace on said wheel body, an outwardly extending beveled rim seat on the inner edge of the wheel body. a demountable rim on said wheel, beveled ribs on the under side of the rinn the rib on the rear side ot the rim being; seated on the said rini seat, the

surt'ace of the wheel having; a depression to receive the valve stem, a driving lug on the surface or the wheel at the side of the depression, the rear beveled rib being cut away adjacent the valve stem opening'to pass over the said lug.
